Sequence alignment of active site residues of the enoyl-ACP reductases from Escherichia coli, Bacillus subtilis, Burkholderia mallei, Yesinia pestis, Clostridium acetobutylicum, Pseudomonas aeruginosa, Variovorax paradoxus, Methylobacillus flagellatus, Erwinia tasmaniensis and Vibrio cholerae. Conserved residues are labeled with an asterix. The sequence alignment was performed using Clustal W (48), and the figure was made using Jalview (49).
